5x-2 = 70
⇒ (x-2) log 5 = log 70
⇒ x = log 70/log 5 + 2
≈ 4.640
(You can use any base you like for the logs, as long as you use the same base for both of them.)

Implicit: x2 + 2y = 5 Explicit : y = (5 - x2)/2
What is x2 plus x2 mean?
If you have an equation of x2 plus x2, it is the same as saying 2 times x plus 2 times x. This can be written as 2x + 2x or x2 + x2. It is the same, then, as 4x. For example, if x equals 5: 2(5) + 2(5) = 10 + 10 = 20. 20 also equals 4(5).
X2 equals 5 what is the value of x?
if x2 = 5 the value of x has to be 5 divided by 2 which is 2.5 x = 2.5
4x squared minus twenty equals zero?
4x2 - 20 = 0∴x2 - 5 = 0∴x2 = 5∴x = √5
